BACKGROUND OF THE INVENTION U.S. Denerich Pat. No. 1,964,936; July 3,1934 discloses a combination padlock having a finger piece which extendsthrough an opening in the lower end of the body, the finger piece to bemanipulated when it is desired to set or change the combination. Thevisible finger piece of this prior art device invites tampering.Combination locks have a curious way of tempting persons to manipulatethem before becoming familiar with the instructions which accompany theproduct. As a result, the combination may be lost, and the product hasto be returned to the manufacturer who expends considerable effort toopen the padlock. Frequently, the product is damaged in the effort tosalvage it.

The padlock disclosed in the aforementioned Denerich patent has thedials located at the bottom end of the lock, or the end opposite the endwhere the shackle is located. The dials are so located in this prior artdevice because of the necessity to use the remaining volume of the bodyto house other elements. Such arrangement does not permit the connectionof a chain to the body of the padlock; the dials are located where thechain would best be connected to the device.

' SUMMARY OF THE INVENTION A combination lock made in accordance withthe invention comprises a body having an internal cavity and a pluralityof spaced slots in communication with the cavity. A dial provided withindicia or numbers is positioned in each slot. A shaft is mounted withinthe cavity, the shaft being mounted for displacement in the direction ofits axis. A sleeve for each dial is mounted on the shaft with thesleeves in abutting, end-to-end relationship. Each sleeve has a flangeand a flat portion. Cooperable means is provided by each dial and itsrespective sleeve for separably keying them together, and spring meansis provided to normally urge the sleeves into keyed relationship withtheir respective dials. A bolt is positioned within the cavity of thebody, and means is provided for normally resiliently maintaining thebolt against the sleeves. A shackle having a long portion and a shortportion is mounted on the body so that the long portion extends into theinternalcavity. As usual, the shackle is moveable to a first openposition and a second closed position. One end of the body is providedwith means to receive the end of the shackles short portion in theclosed position of the shackle.

The long portion of the shackle and the shaft for the sleeves and dialslie substantially in the same plane with the longitudinal axis of theshackles long portion extending perpendicular to the longitudinal axisof the shaft. Cooperable means are provided by the shackle and the boltwhereby the shackle is prevented from longitudinal movement when theshackle is in closed position and the bolt is displaced by a flange on asleeve.

To enable changing or setting of the combination to a combination ofones own personal and secret choice, the free end of the long portion ofthe shackle is provided with cam means, such cam means being cooperablewith the end of the shaft to displace the shaft and disengage thesleeves from their respective dials.

An object of the invention is to provide a combination padlock whicheliminates obtrusive or visible means for changing the combination.

Another object of the invention is to provide a combination padlockhaving a minimal number of rugged parts to thereby furnish a combinationpadlock suitable for heavy duty. I

A further object of the invention is to provide a combination lockincluding means for changing the combination to a combination of one sown personal choice, the padlock being constructed so that the essentialshackle is formed to provide a cam which is used to change or set thecombination.

Still another object of the invention is to provide a combinationpadlock wherein the combination elements or dials and their associatedsleeves are situated within the body and related to the shackle in amanner to permit the body to act as a base for the connection thereto ofa chain without unduly increasing the size of the'product.

These, and other objects and advantages of the invention will beapparent from the following detailed description, taken in conjunctionwith the drawings.

, "DESCRIPTION OF THE PREFERRED EMBODIMENT I is related to the dials tofurnish controlled rotation of the dials. .The sleeves D are mounted ona shaft F with the sleeves in abutting, end-to-end relationship.

In the embodiment of the invention illustrated the combination lockingmeans includes four dials C. With four dials each having ten indicia ornumbers thereon, there are ten thousand different possible combinationsavailable. It will be understood that any desired number of dials may beused to furnish the desired number of available combinations.

The structure of the dials and of the sleeves and their relationship toone another are essentially the same as disclosed in US. Gehrie Pat. No.3,416,338 granted Dec. 17, 1968. The dials C are each provided withindicia or numbers in equidistantly spaced relation on the outercircumference. Between adjacent numbers there are grooves 24 adapted toreceive means provided by the dial cooperable means or spring member E(FIGS. 3 and 4) so that the dials when related to their respectivesleeves D and mounted on the shaft F may be resiliently maintained inselected circumferential position.

As shown in FIG. 10, each dial C has a central opening 26 through whichthe shank 28 of a sleeve D may be extended with a slight amount ofclearance (FIGS. 2 and 7). The sleeve has a central bore 30 of adiameter slightly greater than the diameter of the shaft F. At one endthereof each sleeve is provided with a flange 32 having a largerdiameter than the central opening 26 of a dial. The flanged end of thesleeve is provided with a flat portion 34. At the juncture of the flangeand the sleeves shank, a detent or detents 36 are provided. On one sideof each dial C, circumferentially arranged detent receiving recesses 38are provided adjacent the opening 26, there being one recess inalignment with each number on the dials outer circumference. Therecesses 38 extend only partially into the side wall of the dial and areadapted to receive the detents 36, whereby a dial and a sleeve may bekeyed or meshed to one another. As shown in FIG. 2 spring means Gsurrounding the shaft F acts to normally urge the sleeves into keyedrelationship with their respective dials.

As shown in FIGS. 1-4, the body A comprises a pair of body or casingmembers 40 and 42 suitably connected to one another. For convenience ofmanufacture including minimizing the number of parts and the number ofassembly operations, it is preferred that the body members be made bydie casting. One body member is provided with a pair of transverselyspaced connecting studs 44, and the other body member is made withaligned spaced openings 46 (FIGS. 3 and 4) through which the connectingstuds are extended. The members are connected to one another by a forcefit of the studs within the respective openings. If desired, theconnecting studs and the aligned openings may be dimensioned so that theconnecting studs are extended through the openings following which theends of the studs are headed over to securely connect the parts to oneanother. A third connecting stud 48 is provided on the centrallongitudinal axis and spaced longitudinally from the aforementionedconnecting studs 44 for additional connecting strength and for anotherfunction to be subsequently described.

With the body members connected to one another as described, theperipheral edges of the intumed sides 50, 50 and 52, 52' (FIG. 2) and ofthe inturned ends 54, 54 and 56, 56' (FIGS. 3 and 4) of the body members40 and 42 are firmly pressed against one another to provide an internalcavity 58. The internal cavity is in communication with a plurality oftransversely spaced slots 60 formed in the face of a body member, themember 40 as shown. The slots each have a dial C positioned therein. Asshown in FIG. 2, the body members are formed or cast so that whenconnected to one another a sliding bearing 62 is provided for one end ofthe shaft F. The opposite end of the shaft is provided with an enlargedheaded portion 64 and the body members are cast to receive, whenassembled, the enlarged head portion of the shaft with a slight amountof clearance to permit the shaft to be reciprocated or displaced in thedirection of its longitudinal axis. The purpose of the displaceableshaft and its headed end will be subsequently described.

The shackle B has the usual J-shape and comprises a long portion or leg66 and a short portion or leg 68 parallel thereto. The legs areconnected by a curved or bent portion 70. The long portion extendsthrough an opening 72 in the body (FIGS. 5 and 6) with a small amount ofclearance and into the cavity 58. The body is provided with an opening74 to receive the end 76 of the short portion 68 when the shackle is inthe closed position shown in FIG. 1. A web 78 of a body member serves asa stop to limit the extent that the shackle may be moved inwardly to theclosed position. The shackle is provided with a notch 80 for cooperationwith a bolt H. Preferably, the shackle is provided with a pair ofnotches, one in each leg of the shackle and in alignment with oneanother.

The bolt H is related to the sleeves D and cooperable with the notches80 provided by the shackle B to lock and unlock the device. As shown inFIGS. 3 and 4, the bolt is mounted for pivotal movement about a fulcrum82 provided by the body or, more specifically, by the body member 42.The bolt has an arm portion 84 on one side of the fulcrum for engagementby each of the sleeves and a second arm portion 86 on the other side ofthe fulcrum related to the shackle. Means is provided for normallyresiliently maintaining the bolt against the sleeves, and for thispurpose a coiled compression spring I is positioned with one end thereofbearing against a locating projection 88 on the arm side 86 of the bolt.The opposite end of the spring surrounds an aligned locating projection90 formed on the underside body member 40.

As shown in FIG. 9, the bolt H is provided with slots 92 to allow thedials to extend therethrough. Where four dials are used the bolt needhave but three slots, the fourth dial-being positioned adjacent one endof the bolt as shown in FIG. 2. The arm side 86 of the bolt is providedwith oppositely extending bar portions 93 which are dimensioned to bereceived with a slight amount of clearance in the notches 80 in the longand short portions 66 and 68 of the shackle. As will also be apparentfrom FIG. 2 the flange portions 32 of the sleeves D are related to theweb portions 94 of the bolt so that when a dial is rotated, theconcomitantly its keyed sleeve is rotated, a flange 32 may apply forceagainst a portion 94 of the bolt to displace the bolt against the actionof the spring I from the position shown in FIG. 3 to the position shownin FIG. 4.

When the sleeves D are all oriented so that the flat portions 34 are inalignment with the bolt H as shown in FIG. 3, the padlock is oncombination. In such relationship of the parts the shackle B may bemoved from the closed position of FIG. 1 to the open position and viceversa. When the device is on combination, the oppositely extending barportions 93 are clear of the notches 80 in the shackle as shown in FIG.3 to allow movement of the shackle. To lock the device or place thepadlock off combination, the shackle is moved to the closed positionshown in FIG. 1, and a dial or dials are rotated to cause a flange orflanges 32 on a sleeve or sleeves to rock the bolt about the fulcrum 82,whereupon the bar portions 93 -of the bolt enter the notches 80 as shownin FIG. 4 to prevent the shackle from being pulled out of the body A.

To effect a change in the combination of to set the device upon a newcombination, the free end of the long portion of the shackle is providedwith cam means for cooperation with the end of the shaft F to disengagethe sleeves D from their respective dials C and allow resetting thesleeves with respect to the dials.

As best shown in FIGS. 1 and 5-8, the shackles long portion 66 isprovided with a flat portion or section 96 at the free end of theotherwise substantially round cross section of the shackle. Referring toFIGS. 1 and 7 it will be observed that the shaft F and the long portionof the shackle lie substantially in the same plane with the longitudinalaxis of the long portion extending perpendicularly to the longitudinalaxis of the shaft. As previously described the long portion of theshackle is moveable in a direction parallel to the longitudinal axisthereof by virtue of the ability of the shackle to move from the closedposition to an open position and vice versa. The movement of the shackleto open position is limited by a stop 98 provided by the body which isengaged by a flange 100 provided on the shackle leg 66 as shown in FIGS.5 and 6. The cam means or flat section is cooperable with the end of theshaft, or the shafts headed portion 64 in a selected rotated position ofthe shackle.

The manipulative steps to change or set the device to a combination ofones own selection is accomplished as follows. With the device oncombination and the shackle pulled out to the open position or to thepoint where the flange 100 engages the stop 98, the shackle is rotated180 about the axis provided by the long portion 66 to the position shownin FIG. 5. Secondly, the shackle is pushed inwardly to the positionshown in FIG. 6. In this position the-flat cam 96 is oriented so that aface thereof is positioned opposite the end of the shaft or the enlargedhead portion. 64 which on its op-' disengagement of the sleeves unlessthe precise procedure above described is followed. In fact, theappearance of the padlock does not suggest that it is of the varietywhich enables an individual to set the combination to a combination ofhis own secret choice.

When the sleeves are all oriented as shown in FIG. 3, the padlock is oncombination". With the padlock in such condition, the dials cannot berotated when the shackle has been pulled out to open position androtated to where the end 76 of the shackle is out of alignment with therecess 74. The dials cannot be rotated because of the back pressurebeing placed on the sleeves D by the bolt B. A bar portion 93 of thebolt bears against the periphery of the long portion 66 of the shackleat an area adjoining the notch 80 or on the periphery of the shacklewhere it has its greatest diameter so that the bolt is maintained in theposition shown in FIG. 3. The dials cannot be rotated to cause the lossof the combination by one who would tamper with the device.

As previously indicated the combination padlock of the invention has theelements thereof arranged or related to one another so that a minimalnumber of rugged parts furnish a product suitable for heavy duty. In thepreferred form of the invention, and as shown in FIGS. 1, 3 and 4, thebody members and 42 are formed or cast so that when they are connectedto one another a tunnel-like opening 106 is provided at the end of thebody opposite the end where the shackle is located. Before assembling orconnecting the body members the end link 108 of a chain L is laid inplace so that when the assembly is completed the chain is connected tothe body at the bottom end of the assembly and below the dials whichappear on one face of the assembly. It will be apparent from the viewingof FIGS. 3 and 4 that a very strong structure is afforded; the link ofthe chain is connected to the padlock by. substantial thickness of metaland by substantial means, though the total volume of the device iscomparatively minimal.

It is believed that the advantages'and improved results of the'inventionwill be apparent from the foregoposite side abuts an adjoiningsleeve Dof the plurality of the end-to-end arranged sleeves on the shaft F.

Thirdly, the shackle is rotated back 90 from the position shown indot-dash line to the solid line position shown in FIG. 7 to furnish thecamming action and thereby cause theshaft F to be displaced and thesleeves D to be unkeyed from the dials C. Now, the

dials maybe rotated to the desired combination follow ing which thedescribed manipulative procedure is reversed to furnish the new selectedcombination.

To assist in maintaining or indexing the shackle in its pulled outposition and in its innermost position. where it is respectively rotated180 and 90, it is preferred to provide a leaf spring K for cooperationwith the flange 100 on the shackle-As best shown in FIG. 8, the leafspring is formed with shoulders 102 and 104 for engagement by the flange100 in the respective positions of the shackle.

The described padlock is practically tamper-proof. To change thecombination one must exactly follow the manipulative procedurehereinbefore described, and following such procedure requires readingthe instructions accompanying the product. The head portion 64 of theshaft acts as an obstacle to prevent the cam 96 from reaching theposition where it may act to cause ing detailed. description of apreferred embodiment of the invention. Various changes maybe madewithout departing from the spirit and scope of the invention as soughtto be defined in the following claims.
